Dental suction adapter

Abstract

A dental suction adapter can include a first tube including a tapered portion and a presenting end, the presenting end being configured to fluidly engage an interior of a mouth, and a second tube including a transition tube connected to the tapered portion of the first tube and a connection taper extending from the transition tube opposite the first tube, the connection taper being configured to be connected to an end of an aspirator tube, wherein the adapter is configured to increase a velocity of air at the presenting end compared to a velocity of the fluid at the aspirator tube.

What is claimed is: 
     
       1. A suction adapter device comprising:
 a unitary tubular member comprising a first tube portion comprising a first end and an opposed second end configured to fluidly communicate with an area and a second tube portion comprising a first end and an opposed second end, said first tube portion and said second tube portion forming a continuous tubular wall defining a fluid channel between said first end of said second tube portion and said second end of said first tube portion, said first tube portion being disposed at an obtuse angle relative to said second tube portion, 
 wherein said second tube portion comprises:
 a connection portion comprising a connection first end and an opposed connection second end, said connection portion further comprising a constant cross-sectional internal diameter from said connection first end to said connection second end, said connection portion further comprising an increasing cross-sectional external diameter from said connection first end to said connection second end configured to be received by said pneumatic suction device; 
 a transition portion comprising a transition first end extending from said connection second end and an opposed transition second end, said transition portion further comprising a constant cross-sectional internal diameter from said transition first end to said transition second end; 
 
 wherein said first tube portion comprises:
 a tapered portion comprising a tapered first end extending from said transition second end and an opposed tapered second end said tapered portion further comprising decreasing cross-sectional internal diameter from said tapered first end to said tapered second end configured to increase a fluid velocity from said tapered first end to said tapered second end; 
 a presenting portion detachable from said tapered portion, said presenting portion comprising a presenting first end extending from said tapered second end and an opposed presenting second end, said presenting portion further comprising a constant cross-sectional internal diameter from said presenting first end to said presenting second end, said cross-sectional internal diameter of said presenting portion being smaller than said cross-sectional internal diameter of said tapered portion at said tapered second end; and, 
 a weakening feature disposed at a nexus between said tapered second end and said presenting first end to detach said presenting portion from said tapered portion; and, 
 
 wherein detachment of said presenting portion increases a cross-sectional internal diameter of said second end of said first tube portion. 
 
     
     
       2. The device of  claim 1 , wherein said weakening feature comprises a circumferential snapping point between said tapered second end and said presenting first end to separate said presenting portion from said tapered portion in response to a tensile force. 
     
     
       3. The device of  claim 2 , wherein said snapping point comprises a circumferential reduction in a thickness of said tubular wall at said nexus between said tapered portion and said presenting portion. 
     
     
       4. The device of  claim 1 , wherein said obtuse angle comprises an angle between 140° and 165°. 
     
     
       5. The device of  claim 1 , wherein said obtuse angle comprises a 152° angle. 
     
     
       6. The device of  claim 1 , wherein said first tube portion defines a first channel portion of said fluid channel, and wherein said second tube portion defines a second channel portion of said fluid channel. 
     
     
       7. The device of  claim 6 , wherein second channel portion is shaped to eliminate eddy currents proximate a transition between said connection portion and said transition portion. 
     
     
       8. The device of  claim 1 , wherein said second tube portion further comprises:
 a collar disposed circumferentially around said transition portion proximate said connection second end. 
 
     
     
       9. The device of  claim 1 , further comprising said pneumatic suction device. 
     
     
       10. The device of  claim 9 , wherein said pneumatic suction device comprises a dental evacuation device comprising an aspirator tube, wherein said connection portion is insertably connected within said aspirator tube, and wherein said area comprises a dental patient's mouth. 
     
     
       11. The device of  claim 10 , wherein said tubular wall of said connection portion is flat from said connection first end to said connection second end and is configured to be smoothly inserted and removed from within said aspirator tube. 
     
     
       12. The device of  claim 1 , wherein said tubular wall of said connection portion is flat from said connection first end to said connection second end and is configured to be smoothly inserted and removed from within said pneumatic suction device.
